UNITED STATES JOSEPH LEWIS I IAMEL, E BUFFALO, YORK.

LADDER FOOT.

Application filed May 14, 1925.

To all whom it may concern Be it known that I, JosnPH LEWIS HAMEL,

a citizen of the United States of America,

and a resident of the city of Buffalo, county of Erie, in the State ofNew York, United States of America, have invented certain new and usefulImprovements in Ladder Feet, of which the following is a full, clear,and exact description.

My invention relates to improvements in nonslipping feet for ladders,and the object 0 the invention is to devise a ground or wall grippingdevice which can be detachably secured to the tops and bottoms 01ladders for anchoring them in position so that they cannot becomeaccidently displaced, and a further object of the invention is toproduce a device of a simple construction which will permit it beingreadily atp tached to and detached from ladders of the standard sizes. Astill further object of the invention is to devise means for retainingthe ground or wall gripping portion of my device at any desired angle tothe ladder to facilitate the erection of the same.

My invention consists of a ladder foot constructed and arranged all ashereinafter more particularly described and illustrated in theaccompanying drawing in which Fig. 1 is a side elevational view of myladder foot, the upper portion of the means for securing it to theladder being broker away.

Fig. 2 is a front elevational view thereof the suction cup which Iprovide as a ground or wall grip, and the socket in which it is securedbeing broken away.

Fig. 3 is a side elevational view of a broken away end of a ladder rail.

Fig. 4 is a side elevational view of one of the plates of my devicewhich is secured to the end of the ladder.

Fig. 5 is an edge elevational view thereof, and

Fig 6 is a broken away side elevational view of the upper portion of thesuction cup socket.

Like characters of reference indicate the corresponding parts in thedifferent views.

1 is a suction .cup having a recess 2 in its lower face, and it reducedcircular portion 3 on its upper face, the cuping of circular shape .aicl' preferably constructed of rubber. 4 is tbefipQka .lt iem er havinga downwardly Serial No. 30,296.

extending skirt 5 on its lower face which forms a socket 6 of circularformation into which the reduced portion 3 of the suction cup isinserted. The socket 6 gradually increases in diameter from its mouthinwardly which permits the portion 3 to swell therein thus firmlysecuring them together.

Upon the upper face of the socket member 4: a pair of upwardly extendingparallel, and spaced apart lugs 7 and 8 are provided, and 9 areopposedly positioned centrally disposed circular orifices in the lugs.10 and 11 are a pair of plates of similar construction having bosses 12on their outer faces in the vicinity of their lower ends, the bossesbeing adapted to be freely inserted into the respective orifices 9. 13are pairs of orifices in the upper ends of the plates, and 14 are a airof similarly spaced apart orifices in the ladder leg 15. 16 are boltsfor bolting the plates 10 and 11 on either side of the ladder leg 15,the bolts passing through the orifices 13 in the plates and 14.- in theladder foot.

Upon the outer faces of the plates 10 and 11 and surrounding the bosses12, and also on the inner faces of the lugs 7 and 8 and surrounding theorifices 9, I provide circular serrated faces 17 and 18, these facescoact one with the other and retain, the lugs and plates in adjustedrelationship with each other. For strengthening the lugs 7 and 8 on thesocket, I provide a cross piece 18 joining them at one side.

In order to attach my device to a ladder it is merely necessary to drilla pair of holes in the ends of the ladder rails as shown in Figure 3,and place the plates 10 and 11 against the inner walls of the lugs 7 and8, the bosses 12 entering the orifices 9. The end of the ladder rail isnow inserted between the plates and the bolts 16 inserted through theorifices 13 in the plates and 14 in the rail end, wing nuts 19 beingscrewed home on the bolts thus firmly securing the plates to the ladderrail end. It is to be understood that in the construct-ion of my deviceit is so dimensioned that the space between the positioned plates 10 and11 will tightly receive the ladder rail end, and through the abutment ofthe serrated faces 17 and 18 the foot can be retained at any desiredangle to the ladder. This feature is particularly desirable when mydevice is d on t e head of the ladder, as it permits the suction cupbeing positioned at the correct angle before the ladder is reared.

From theabove description it will be seen that I have devised a simplyand cheaply constructed foot for step ladders pairs of Which can be veryreadily applied to any standard ladder at a minimum of cost and time.Furthermore by my construction the feet may be quickly detached from oneladder and attached to another.

\Vhat I claim as my invention is:

A ladder toot, comprising a socket niember, a suction cup secured to thesocket member, a pair of lugs having orifices therein and extendingupwardly from the socket member, and a pair of plates having bossesthereon adapted to be detachably secured to a ladder rail, the bossesbeing adapted to be inserted into the orifices in the lugs.

JOSEPH LEWIS HAMEL.
